1.as you said you are unmarried so 'performance anxiety' is ruled out.
2.any psychological trauma??
3. reduce the sensation of glans, by applying Lignocaine ointment, or by wearing a condom.
4. divert the mind to non-sexual activities like sports or business matters.
5. If Premature Ejaculation is gross you need to see a Doctor for proper counselling and who will help you to develop ejaculatory control.

Hello Umar;
Welcome to HealthcareMagic
Premature ejaculation is more mental problem than a physical disease .Since you are unmarried at 38 may be you have few issues with in your mind ;overworked ;too much mental pressure.If you have any of these first try to find a solution to your problems .As for increasing the time you can try to stop for a minute just before ejaculation & restart sexual act again.This is called start stop method it will definitely help you increase your time.
Take care
Thanks

Dear Umar
Many a times over excitation or lack of confidence and fear of failure or feeling of insult is the reason that leads to such a situation. it can be easily cured, first forget about it and enjoy the act instead of testing it as a success or failure. If you are in pakistan you can have majun aihtlam initially and after it have majun mugalaz.

Dear
welcome to healthcaremagic
There are many factors for this, excess masturbation, Stress, Anxiety,Etc. I suggest you some tips for your solution
Change of Diet: Follow a low cholesterol diet if you have a high cholesterol. Keep sugar intake low if you have diabetes as men with this problem tend to experience premature ejaculation.
Almond milk:Adding saffron, an aphrodisiac, to this milk drink makes it an effective remedy.
You need:
10 almonds
a cup of hot milk (cow’s milk)
saffron
pinch of ginger
pinch of cardamom
Vidari
Bala
Ashwagandha
Add ½ teaspoon of this mixture to warm goat’s milk.
Try the following yoga asanas exercises:
The Bow, Fish, and Camel poses
Elevated Lotus
Vajrasana
Regular massage to the penis helps improve blood circulation and stimulate the muscles, dilating the blood vessels and using the mustard oil has a heating effect that’s more effective.

Thanks
